The UKMTO have issued a warning on behalf of the JMIC, reporting that a United States-flagged container vessel was approached by two small military craft whilst underway in the Persian Gulf (exact position not specified). The craft hailed the vessel, requesting details on personnel and the next port of call, but the Master did not respond to these inquiries. The military craft persisted, maintaining position off the vessel’s starboard quarter and hailing via VHF Channel 16. The Master identified the vessel’s flag state, and stated the vessel was operating in accordance with international law. All crew were secured and accounted for in the accommodation block with additional mates on the bridge. The military craft continued to hail and at 1323 UTC, they crossed the vessel’s bow closely, repositioning to the port beam and quarter, before aborting their pursuit at 1324 UTC. It is advised that vessels operating in the area take all appropriate precautions and industry recommendations.
